3.Check the air pressure in all four tires at the
next opportunity.
If the tire inflation pressure in all four tires is
shown to be correct, it is possible that the
Tire Pressure Monitor did not perform a re‐
set. Then perform the reset.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on cargo load, driv‐
ing style and road conditions.
A vehicle with an average load has a possible
driving range of approx. 50 miles/80 km.
A vehicle with a damaged tire reacts differently,
e.g., it has reduced lane stability during brak‐
ing, a longer braking distance and different
self-steering properties. Adjust your driving
style accordingly. Avoid abrupt steering ma‐
neuvers or driving over obstacles, e.g., curbs,
potholes, etc.
Because the possible driving distance depends
on how the vehicle is used during the trip, the
actual distance may be shorter or longer de‐
pending on the driving speed, road conditions,
external temperature, cargo load, etc.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
Your car handles differently when you lose tire
inflation pressure, e.g., your lane stability is re‐
duced when braking, braking distances are lon‐
ger and the self-steering properties will
change. ◀
Final tire failure
Vibrations or loud noises while driving
can indicate the final failure of a tire. Reduce
speed and stop; otherwise, pieces of the tire
could come loose and cause an accident. Do
not continue driving and contact your service
center. ◀
Required inflation pressure check
message
A Check Control message is displayed in the fol‐
lowing situations▷The system has detected a wheel change,
but no reset was done.▷Inflation was not carried out according to
specifications.▷The tire inflation pressure has fallen below
the level of the last confirmation.
In this case:
▷Check the tire pressure and correct as
needed.▷Carry out a reset of the system after a tire
change.
System limits
The system does not function properly if a reset
has not been carried out, e.g., a flat tire is re‐
ported though tire inflation pressures are cor‐
rect.
The tire inflation pressure depends on the tire's
temperature. Driving or exposure to the sun
will increase the tire's temperature, thus in‐
creasing the tire inflation pressure. The tire in‐
flation pressure is reduced when the tire tem‐ perature falls again. These circumstances may
cause a warning when temperatures fall very
sharply.
Malfunction The yellow warning lamp flashes and
then lights up continuously. A Check
Control message is displayed. No flat
tire or loss of tire pressure can be detected.
Display in the following situations:
▷A wheel without TPM electronics, such as
an emergency wheel, is mounted: have the
service center check it if needed.▷Malfunction: have the system checked by
your service center.Seite 83SafetyCONTROLS83

▷TPM was unable to complete the reset. Re‐
set the system again.▷Interference through systems or devices
with the same radio frequency: after leav‐
ing the area of the interference, the system
automatically becomes active again.
Declaration according to NHTSA/FMVSS
138 Tire Pressure Monitoring System
Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.) As
an added safety feature, your vehicle has been
equipped with a tire pressure monitoring sys‐
tem (TPMS) that illuminates a low tire pressure
telltale when one or more of your tires is signifi‐
cantly under-inflated. Accordingly, when the
low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Un‐
der-inflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle's han‐
dling and stopping ability. Please note that the
TPMS is not a substitute for proper tire mainte‐
nance, and it is the driver's responsibility to
maintain correct tire pressure, even if under-in‐
flation has not reached the level to trigger illu‐
mination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approxi‐
mately one minute and then remain continu‐
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not be
able to detect or signal low tire pressure as in‐
tended. TPMS malfunctions may occur for a va‐
riety of reasons, including the installation of re‐
placement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the re‐
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
FTM Flat Tire Monitor
The concept The system does not measure the actual infla‐
tion pressure in the tires.
It detects a tire inflation pressure loss by com‐
paring the rotational speeds of the individual
wheels while moving.
In the event of a tire inflation pressure loss, the
diameter and therefore the rotational speed of
the corresponding wheel changes. This will be
detected and reported as a flat tire.
Functional requirements The system must have been initialized when
the tire inflation pressure was correct; other‐
wise, reliable flagging of a flat tire is not as‐
sured. Initialize the system after each correc‐
tion of the tire inflation pressure and after
every tire or wheel change.
Status display
The current status of the flat tire monitor can
be displayed, e.g., whether the RPA is active.1. Press button.2. "Vehicle Info"3."Vehicle status"4."Flat Tire Monitor (FTM)"

InitializationWhen initializing the once set inflation tire pres‐
sures serve as reference values in order to de‐
tect a flat tire. Initialization is started by con‐
firming the inflation pressures.

snow chains.1. Press button.2. "Vehicle Info"3."Vehicle status"4."Flat Tire Monitor (FTM)"5.Start the engine - do not drive off.6.Start the initialization with "Flat Tire
Monitor (FTM) reset".7.Drive away.
The initialization is completed while driving,
which can be interrupted at any time.
The initialization automatically continues when
driving resumes.
Indication of a flat tire The yellow warning lamp lights up. A
Check Control message is displayed.
There is a flat tire or a major loss in tire
inflation pressure.
1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with
regular tires or run-flat tires.
Run-flat tires, refer to page 184, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire's sidewall.
Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents. ◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if needed.
System limits Sudden tire damage
Sudden serious tire damage caused by
external circumstances cannot be recognized in
advance. ◀
A natural, even tire inflation pressure loss in all
four tires will not be recognized. Therefore,
check the tire inflation pressure regularly.
The system could be delayed or malfunction in
the following situations:▷When the system has not been initialized.▷When driving on a snowy or slippery road
surface.▷Sporty driving style: spinning traction
wheels, high lateral acceleration (drifting).▷When driving with snow chains.
Actions in the event of a flat tire
Normal tires
1.Identify the damaged tire.
Do this by checking the air pressure in all
four tires.
The tire pressure gauge of the Mobility Sys‐
tem, refer to page 185, can be used for this
purpose.
If the tire inflation pressure in all four tires is
correct, the Flat Tire Monitor may not have
been initialized. In this case, initialize the
system.
If an identification is not possible, please
contact the service center.2.Fix the flat tire using the Mobility System,
refer to page 185.Seite 85SafetyCONTROLS85
